Embodiment Construction

[0023] The hyperbolic steel support for engineering structures of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0024] Such as figure 1 and figure 2 As shown, the hyperbolic steel support used for engineering structures includes an upper cover 1, a central core 2, a base 10 and a fixed box 14. The lower part of the central core 2 is a hyperbolic spherical crown with a radius of curvature of R1. The radius of curvature in the vertical direction is R2, R2<R1, and the center of the upper surface of the base 10 has a hyperbolic concave cavity corresponding to the curvature of the central core, and the hyperbolic lower surface of the central core 2 is located in the concave cavity of the base 10. There is a polytetrafluoroethylene backing plate 11 between the center core and the base to reduce the friction force when the center core rotates in the cavity. The bottom of loam cake 1 has a concave ho...

Abstract

This invention discloses a hyperbolic steel support used in engineering structure including a cover, a core at the lower surface of the hyperbolic surface, a base seat and a fixed box of its reentrant at the upper surface of the core between the top cover and base seat keying together the lower part of the cover and upper part of the base seat, a flexible absorber is between the surrounding sidewall of the top cover and fixed box having a guide rail at the bottom to make the base seat slide on it only. There are Teflon boards between top cover and core, base seat and fixed box bottom, and core and the base seat, sealing plates seal the open-end at top of the fixed box cover and three siamese sealing rings sealing between the cover and base seat.

Description

technical field [0001] The invention relates to an engineering structure component, in particular to a support for an engineering structure. Background technique [0002] In the design and construction of bridges and building engineering structures, the impact of earthquakes, vibrations, temperature changes, and wind forces on engineering structures must be taken into account. The support is a structural vibration damping element widely used in engineering construction, especially in bridge engineering. It not only transmits the gravity of the upper and middle structures of bridges and other building structures to the lower structures such as piers and columns, but also has the functions of vibration reduction, anti-corrosion pull out, release bending moment, anti-displacement, etc. [0003] At present, the supports used in engineering structures mainly include rubber bearings and steel bearings. Rubber bearings have good vibration reduction effects, but they are prone to a...
